' WATER-FEED ATTACHMENT FOR ELECTROLYTIC CELLS.

Application filed April 21, 1919. Serial No. 291,643. Renewed April 23, 1920. Serial No. 376169 T 0 all whom it may concern:

Be it known that I, IsAAo H. LEVIN, a citizen of the United States, residing at the borough of Manhattan,-in the city, county,

and State of New York, have invented certain new and useful Improvements m lVater-Feed Attachments for Electrolytic Cells, of which. the following is a specification, reference being had therein to the ac companying drawings, which form a part thereof.

My invention relates to water feed attachments for electrolytic cells, and more particularly to a type thereofivherein the-fill cup is utilized to permit a blowout in the event of the development of excessive pressures in a cell, or of the level of the electrolyte in the cell becoming too low;

In attachments of the type to which my invention relates, there is a chamber adapted to contain feed water, which chamber communicates, through suitable passages, with the interior of a cell,one end of said passages terminating within said chamber, and

the other end thereof being normally below the level of the-electrolyte in said cell, so

that under normal conditions both endsof the passage are sealed against the escape of gases by the solution in the cell, or the feed Water in the chamber. In the event of the electrolyte in the cell get-ting too low, or the development of excessive pressures in thecell, gases from the cell will escape through the said passages betweenthe cell and the feed water chamber, these gases being imprisoned by the electrolyte in the form of small bubbles, which emerge from the passages with sufiicient velocity to spatter electrolyte upon the exterior of the cell.

In a device made in accordance with my invention, the gas bubbles, or spray, are permitted to flow freely through the said passages into the said chamber when conditions within a cell are such as to cause a blow-out, means being provided, however, whereby the various small bubbles will be confined within the chamber in a manner to cause them to merge into larger bubbles, said means being so constructed that when said larger bubbles burst, the gas therein will be permitted to escape, but the liquid of the envelop thereof will be returned to the chamber, thus preventing the splashing of this liquid, or the escape of the spray formed by the bubbles, in a manner to foul the cell. I

within the chamber, which baflle has gas.

passages therethrough, a perforated shield mcloslng said baffle in a manner to cause the accumulation of gas bubbles upon the under side thereof with the results above referred to.

The invention consists primarily in a water-feed attachment for electrolytic cells embodying-therein means forming a chamber for feed water, and passages leading from said chamber and discharging within sa d cell, and a perforated shield within said chamber and above the ends of said passages, whereby gas bubbles emerging from sa d passages will accumulate upon the under side of said shield, and gas. freed b the bursting of bubbles will pass throug said shield and the liquid envelop of said 'bubbles will be returned to said chamber; and 1n such other novel features of construction and combination of parts as are herein Specification of Letters Patent. Patent d N 30 1920 after set forth and described and more par- Fig. 3 is a detailed view of the end of the fill pipes within the cup and the baffle and shield upon a larger scale; Fig; 4 is a plan View of Fig. 5 is a plan view of the shield. Like letters refer to like parts throughout the several views.

A water feed attachment made in accordthe bailie;vand

In the accompanying drawings, I have illustrated it in connection with a uni-polar generator of the multiple unit type. wherein the-cell casing is insulated from the electrodes and 1s surmounted by a fill cu with the interior of the cel through suitably communicating a iiionsof I'm? sbwhl being sufiicientiy small to prm'em (be @scape of bubbles; Etheretblmlgb {bus musing such bubbles t 21c .izzt Hi my inwnifirm slumn (71 inflate on the ulukr side 013 x1113 shield, j w the zzi'tzu'bnlent is JW'D as \vhew as a result 01" Contact: with each.
